Hannover/inns' 1N HAND-STAMPS.

The Schedule referred to :In these Letters Patent and making part of the same.

. Be it known that I, NATHANIEI; L. OHAMBERLAJN, of Boston, in the county of Suffolk, and State of Massachusetts, `have invented certain new and useful Improvements in Hand-Stamps, of which the followingis 4 a clear, full, and exact description, reference being had tothe accompanying drawings, making a part oi' this specification, in whichi' Figure 1 represents a side elevation of a hand-stamp embodying my improvement; f

Figure 2 is a front elevation ofthe same; Figure 3 is a transverse vertical section; and Figure 4 represent side elevations and end views of the type-wheels.

The nature of my invention consists in the employment of threetype-wheels, of `equal diameter, so constructed and arranged that each will readily indicate vthe proper character of the date to be printed.

The invention also consists in a peculiar method of attaching the saddle, or portion which carries the wheels, to the handle, so that the wheels maybe readily turned horizontally, and enable an impression to be made in any desired position.

The invention further consists in constructing the lower ends of the saddle with anges, to which is secured the die-holder.

The invention also consists in 'an arrangement, whereby one detent is made to secure in position two of the three type-wheels.

Referring to the drawings, wa represent the base of an upright stamp, provided with the cushion a', of the usual construction. An armor-standard, b, extends at an angle upwards, and Asustains on its upper end a cylindrical sleeve o, inwhich is arranged a hollow plungend, the latter being held in an elevated position by means of a spring, in the usual manner. It is frequently desirable to stamp an impression on a paper or document, which cannot be readily operated upon in the ordinary hand-stamp, in consequence of the dievplate being in a xed position relatively to its vertical axial line. 'lo overcome this diiculty, Ifattach to the handle e, a shait or spindle, f, tlg. 3, which'extends downwards, and is provided at its lower'end with a thread, which screws into the head ofthe saddle h, as seenin dg. 3, so that by loosening the shaft f,.tlie saddle containing the type-wheels may be turned roiuid upon its axis, and enable an impression to be made in any desired position. gis a washer,` of rubber or other suitable material, for the purpose of relieving the concussion of the saddle and cylinder c, when a blow. is struck on thev handle.

fm, 1tA o represent the three type-wheels, `all of the same diameter, and provided respectively, on their ,perimeters, with the properA numbers and letters to mark the year, month, and day. They are each provided on their sides .with corresponding numbers or letters, so arranged that by means of pointers or indicators suitably arranged, the position of'each wheel to print the proper date or number may be readily 'indicated.

In order that this may be effected by all the wheels,

the outer wheel on one side consists simply of a ring,- as seen at on, in iig. 4, and the central wheel, n, is

formed or provided with a projection or hub, n', of a diameter equal to the interior opening of the ring m, and of an equal thickness of the same, in which it fits snugly, but so as to rotate freely. may form a part of or be connected to the portion n, in any suitable manner, so as to rotate with it. The central wheel n is designed ibrprinting the days of the month, and on the projecting portion n of the same are the equivalent numbers for indicating those to be printed. On the ring or wheel amare marked the years, and on the same are also marked the words paid, and cash, and also the initials A. M. and P. M. o is the wheel designating the months, and provided with the indicating-letters on the side. The wheels are held in position by means ofthe springspins p and q, engaging in holes in the wheels. The pin q passes entirely through the outer ring m, into "the central wheel u, so that by pulling`- out the said pin partially, the inner or central wheel may be moved, andl set in any desired position, and on pulling it out fin'ther, the outer wheel may be moved and set.

On the lower portion oi' the saddle or wheel-holder h, are flanges i i, extending from each side, as shown in figs. @and 3, and provided with screw-holes, by meansv of which the die-plate is secured tothe saddle.

The dang-es on the sa'ddle or wheel-holder serve an important purpose, inasmuch as without themit would be necessaryto construct the die-holder with a Hauch, or insert screws up through the die-holder into the under side of the saddle, in which case the portion containing the wheel would hL ve to be removed. By this means, I am enabled to readily attach and detach the die-holder, as desired. l l are `the eases containing the ribbon-reels;

It will thus be seen that a very compact and easilyadjusted hand-stamp is produced, and one that may readily be adapted to all` the various uses required in hand-stamps.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a three type-.wheels of equal diameter, each provided with exposed gures or letters upon their sides, substantially as and for the purpose set forth.

2. Securing the saddle or type-wheel holder to the plunger, by means of 'a screw-bolt, substantially as and for the purpose specified.-

3. Constructing the saddle or type-holder with danges 'i i, as and for the purpose described.
